how to calculate signal width in a cellView

Hi Vincent

I think there are not too many details in your question so I am going to guess a little. I will guess that you need only the info for top level interconnects. : P  The following script will send width info of all the top level shapes to a text file. Hope that you can improve on it to do what you want. When posting a question, it would be great if you can state the specific version of Virtuoso which you are using.

unix>icfb -W
unix>virtuoso -W

Load the script and press F10 in a layout. Look for the output file "sigWidth.txt".

Best regards

procedure( CCSsigWidth()
   let( (cv outPort sName sWidth)
      cv=geGetWindowCellView()
      outPort=outfile("sigWidth.txt")
      fprintf(outPort "Signal Name\tWidth\n")
      fprintf(outPort "===========\t=====\n")
      foreach(shape cv~>shapes
         sName=shape~>net~>name
         sWidth=shape~>width
         if( sName && sWidth then
           fprintf(outPort "%s\t%g\n" sName sWidth)
         ) ;if
      ) ;foreach

      close(outPort)
      outPort=nil
      printf("Signal width info has been sent to file sigWidth.txt")
   ) ;let
) ;procedure

hiSetBindKey("Layout" "F10" "CCSsigWidth()")
